Please help me what shall I do?

So i ve been datin this guy for months now and lately he seemed always busy and so and i have the feeling that he lost interest in me.. its been a long while since last time we went out for dates yet he still cares for me (like he does to others) barely flirt with me.. now that i am quiet depressed, i told him that he is making me feel lonely and this was his answer:
"Try to foccus on your studies or like find any sort of activities to fullfill your time and it would be beneficial for you and you ll see i ve never meant to be careless "
He made me feel like i m wasting his time while i already have lot of things i m doin already.. that made me feel hella upset it's like
He feels bored with the relation.
Please help me what shall I do?
